Researchers at the University of Zurich have developed epigenetic drugs that can reprogram perivascular fat cells to reduce inflammation and improve blood vessel health. By targeting specific gene-expression regulators, these drugs aim to prevent vascular damage in people with obesity and metabolic disease.
Researchers at UT MD Anderson Cancer Center have made significant advancements in targeted therapy treatments for advanced lung cancer and early-stage classical Hodgkin lymphoma. The studies showcase high response rates with novel combination therapies and a new understanding of how an enzyme affects infertility and cancer progression.
Researchers developed RF-SIRF, a quantitative method to detect and map reversed DNA replication forks with single-cell resolution. The study identified unique epigenetic codes for DNA replication stress that can be further examined to understand genomic stability, aging, and treatment response.
Researchers mapped epigenome changes in cells that regulate blood sugar levels, finding patterns differ between people with and without type 2 diabetes. Epigenetic alterations impact insulin-producing beta cells, leading to impaired energy production and reduced insulin release.
Researchers discovered Setd8 enzyme preserves retinal progenitor cell flexibility, enabling potential regenerative vision therapies. The study highlights a potential target for repairing damaged retinas, with implications for regenerative medicine and ophthalmology.
A new study found that a single toxic fungicide exposure during pregnancy can increase the risk of disease for 20 subsequent generations, with inherited health problems worsening over time. The study suggests that epigenetic disease inheritance could help explain rising chronic disease rates in humans.
Dr. Maria Margarita Behrens' work deciphers the molecular signatures defining every human brain cell type, shedding light on neural development and psychiatric disorders. Her single-cell epigenomic atlases will enable researchers to target specific cell types with unprecedented precision.
Scientists at the Salk Institute have discovered a new mode of epigenetic targeting in plant cells, where specific DNA sequences guide DNA methylation patterns. This finding has major implications for understanding epigenetic regulation and could inform future strategies for epigenetic engineering.
Scientists at the University of Leicester discovered that jewel wasps can slow down their biological rate of ageing by undergoing a natural 'time-out' as larvae. This pause in development extends lifespan and decelerates the epigenetic clock, tracking chemical changes in DNA.
A recent study published in The EMBO Journal reveals that the Setd8 gene plays a critical role in the premature aging of the brain by controlling neural stem cell activity and proliferation. Artificially lowering Setd8 levels mimicked molecular signatures of aging, highlighting its potential as a biomarker for early aging.
Researchers discovered temperature influences plant cell fate by regulating epigenetic marks. Low ambient temperatures can rescue developmental defects by compensating for PRC2 loss, highlighting the importance of H3K27me3 in maintaining cellular identity.
Researchers at UC Santa Cruz engineered cellular models of embryos using CRISPR technology, allowing them to study early developmental stages without experimenting with actual embryos. The team found that 80% of stem cells organized into embryo-like structures, showcasing a remarkable collective behavior and molecular composition.
Peter A. Jones, Ph.D., D.Sc., receives a seven-year, nearly $7.9 million grant to study epigenetic errors driving cancer development and explore potential new treatments. The funding will support his research into the molecule DNMT3A, which is involved in brain development and cancer development.
Researchers developed a new biological age indicator, DNAmFitAge, that incorporates physical fitness parameters, showing a correlation with lower mortality risk, coronary heart disease risk reduction, and improved disease-free status in physically fit individuals.
Researchers from the ALFA Score Consortium explore how nutrition and physical exercise can positively impact the aging process by modifying epigenetic changes. They find that healthy aging is associated with more tightly condensed chromatin, fewer histone post-translational modifications, and greater regulation by non-coding RNAs.
Researchers found epigenetic changes in post-COVID patients, including genes associated with taste and smell, as well as cell metabolism. These findings may lead to the development of new diagnostic tools for this and similar diseases.
Exercise promotes a molecular profile consistent with expression of youthfulness-promoting Yamanaka factors, according to a recent study published in the Journal of Physiology. The researchers found that exercise induces Myc protein in muscle, which may serve as a naturally induced reprogramming stimulus.
A new diagnostic marker has been identified that predicts successful and efficient oocyte development. The study found that X-chromosome inactivation and reactivation are critical for normal germ cell differentiation.
Researchers at the University of Illinois Chicago found that gene editing can reverse epigenetic changes in the brain caused by adolescent binge drinking, leading to a decrease in anxiety and excessive drinking behavior. The study used CRISPR-dCas9 technology to manipulate histone acetylation and methylation processes at the Arc gene.
A study found that early exposure to estrogen or BPA increases the risk of precancerous lesions in the prostate. Researchers discovered that this leads to epigenetic reprogramming, altering gene expression patterns that promote prostate disease with aging.
